Which example of peer feedback for a work of narrative fiction is most effective?

A. Some of the story elements are good, but most of the things in the
story are bad or just O. K.

B. This story may be effective, but it belongs to the horror genre, which is the least creative genre.

C. Instead of writing a love story, you should have written a story
about a sea captain and his crew.

D. I wanted a better sense of the setting. What does the character see, hear, smell, and feel?
